1999 Durango 4wd SLT Problems

From : montezuma336

Q: are there any reasons to not putting rod and/or main bearings in or is a short block the only way to go assume this is the gas v8 if you have a knocking from the engine it could be a rod but also could be wristpin related or piston slap. youll need to diagnose the actual problem first. however if its rod bearing related simply putting in another set of bearings isnt the best idea until checking to see 1 what caused the problem lack of oiling due to clogged passageway 2 if the crank journal meets acceptable specs isnt out of round or worn down 3 that the rod meets specs isnt out of round bolts intact 4 no other problems due to metal floating in the oil. 5 oil pump is performing to spec given the possibilities it may be quicker and easier once a definite diagnosis is made to go with a short block. -- max give a man a match and he is warm for a short while. light him on fire and he is warm for the rest of his life. the 5.9l motor in my 98 2500 quad cab has developed a lower end knock. its most noticeable on start for a few seconds but its always there just much quieter. this truck has about 100k on it. my thought is a rod bearing but i guess it could be a main bearing. other than this the motor runs strong. we pull a 5000 pound trailer about 200 miles every weekend for several months. were looking to possibly be pulling for longer distances next year. are there any reasons to not putting rod and/or main bearings in or is a short block the only way to go thanks for any suggestions. .
